I’m want my iPhone software update

iPhone 6, iOS 12

iOS 12.5.7 is the latest iOS security update for iPhone 6.

Go to Settings -> General -> Software Update -> Download and Install (if you haven't already done that).

iPhone 6 can’t be update to a higher iOS (13 and later). 

If you have an outdated iPhone that cannot be updated to iOS 13 or later, many apps will not be able to download.

Outdated iPhone no longer meets the requirements for many apps.

Most apps require iOS 13.4 or later.
